Hello,
There's little detail you need to be aware of when working with PPR. This is
not directly linked to the issue, but rather to the suggestion. Trinidad
uses tr:body as PPR root. Therefore, anything placed outside body won't be
PPR-able, even if it's a homemade component supporting PPR.
As for the main issue itself, you could also use the partialTriggers
attribute on the component you want to refresh on dialog return. The result
will be the same as Srinath's suggestion, but you won't have to write any
Java code.
Regards,
~ Simon

Sorry for a Wrong tip. viewRoot doesn't render anything and hence it
cannot be added as a partial target. One simple solution could be wrap all
your contents with a panelGrouplayout component and add it to the partial
target.
You can use the binding attribute to get the instance of the
panelGroupLayout or any other component in your managed bean
<tr:panelGroupLayout binding="#{DialogMB.panel}">
..
</tr:panelGroupLayout>
in your managed bean
CorePanelGroupLayout panel; and a getter and setter for the same.
-Thanks,
Srinath K
